JS 禁止Ctrl+C + 禁止右键操作

<script type="text/javascript">
    document.oncontextmenu = new Function("return false");
    document.oncontextmenu = function () { return false; };
    document.onkeydown = function () {
        if ((window.event && window.event.keyCode == 123) || ((event.ctrlKey) || (window.event.keycode == 67))) {
            event.keyCode = 0;
            event.returnValue = false;
            return false;
        }
    };
</script>

记录！
